Phonograph record



Patented June 21, 1932 UNITED STATES PATENT OFFICE PHONOGRAPH RECORD Application filed m a, 1930. Serial No. 450,692.

The present invention relates to records, anals more particularly to phonograph recor One of the chief charms obtainable from the phonograph is to listen to the music quietly and restfully in subdued light. The musical selections are frequently of such length that they are continued on the other side of the record and even upon successive records. The order of succession is indicated visually upon suitable labels carried by' the records. In order to play the selections in proper order, therefore, it becomes necessary to increase the light in the room, and this dispels the enchantment.

It is an object of the present invention, therefore to provide, in an exceedingly novel and simple manner, for tactually distinguishing the successive selections, thereby making it possible for one to enjoy the music without the successive interrupting shocks caused by periodic illumination of the room.

Other and further objects will be explained hereinafter.

With these ends in view, the invention consists of the improved record a preferred embodiment of which is hereinafter described, illustrated in the accompanying drawing, and defined in the appended claims.

In the drawing, Fig. 1 is a view of one side of a phonograph record embodying the present invention; Fig. 2 is a fragmentary view of the reverse side; Fig. 3 is a section, upon the line 33 of Fig. 1, looking in the direction of the arrows; Figs. 4 and 5 are yiews corresponding to Figs. 1 and 2, respectively, of a modification; and Fig. 6 is an edge view of the record shown in Fig. 1.

The phonograph record 2 is prc vided upon one side of its smooth central portion 4 with a projection 6. The other side 8 may be rovided with two projections 10. Merely by touching the projections 6 and 10, therefore, it is possible to determine, without the aid of light, which side of the record contains which selection. The side having the single projection 6, for example, may have the first part of the selection, and the side having the two projections 10 the second part of the selection.

If the selection is so long as to require more than one phonograph record, another record 12 may have three projections 14 on one side and four projections 16 on the other side or, if desired, the record 12 may be complete within itself; that is, without being a continuation of another record. The proj ections 14 and 16 make it possible tactually to distinguish between opposite sides of the record.

The invention is obviously not restricted to the exact embodiments thereof illustrated and described herein, but modifications may be made by persons skilled in the art without departing from its spirit and scope as defined in the appended claims.

What is claimed is:

1. A record having two sides, each having a record sound track, and means for tactually distinguishing the sides.

2. A record having two sides, each having a record sound track, and projections) or difi'ering characteristics on the two sides for tactually distinguishing the sides.

3. A record having two sides, eachhaving a record sound track, and projections on the two sides, the projections on one of the sides being greater in number than on the other side for tactually distinguishing the sides.

4. A record having two sides, a projection on one of the sides and two projections on the O tllIGI side for tactually distinguishing the si es. 7

5. A series of records each having two sides, the sides having projections in numerically progressive order for tactually distinguishing the sides.

6. A double-sided sound-record disc wherein surfaces of the opposite sides are differently formed at parts outside the record trace, whereby one side can readily be dis-' tinguished from the other in alight too weak to read printed matter.

7 A double-sided sound-record disc in which the opposite sides of the disc are distinguished from each other by means which can be recognized bv touch, situated on part of the record other than the annular space occupied by the recorded portion of the disc.

8. A double-sided sound-record disc in which the (gposite sides of the disc are distinguished om each other by means of projections which can be recognized by touch, situated on part of the record other than the annular space occupied by the recorded portion of the disc.

In testimony whereof, I have hereunto subscribed my name.

EDWARD L. BOWLES.
